Detailed Description

Macro Definition Documentation

◆ SIP_CONTACT_INIT

#define SIP_CONTACT_INIT ( )

Initializer for structure sip_contact_t.

A static sip_contact_t structure for Contact header must be initialized with the SIP_CONTACT_INIT() macro. For instance,

#define SIP_CONTACT_INIT()
Initializer for structure sip_contact_t.
Definition sip_protos.h:2766
#define sip_contact(sip)
Access a SIP Contact header structure sip_contact_t from sip_t.
Definition sip_protos.h:2749
Structure for Contact header field.
Definition sip.h:473

◆ SIPTAG_CONTACT

#define SIPTAG_CONTACT (   x)

Tag list item for pointer to a Contact header structure sip_contact_t.

The SIPTAG_CONTACT() macro is used to include a tag item with a pointer to a sip_contact_t structure in a tag list.

Parameters
xpointer to a sip_contact_t structure, or NULL.

The corresponding tag taking reference parameter is SIPTAG_CONTACT_REF().

◆ SIPTAG_CONTACT_STR

#define SIPTAG_CONTACT_STR (   s)

Tag list item for string with Contact header value.

The SIPTAG_CONTACT_STR() macro is used to include a tag item with a string containing value of a sip_contact_t header in a tag list.

Parameters
spointer to a string containing Contact header value, or NULL.

The string in SIPTAG_CONTACT_STR() can be converted to a sip_contact_t header structure by giving the string s has second argument to function sip_contact_make().

The corresponding tag taking reference parameter is SIPTAG_CONTACT_STR_REF().

Function Documentation

◆ sip_contact_add_param()

int sip_contact_add_param ( su_home_t home,
sip_contact_t m,
char const *  param 
)

Add a parameter to a Contact header object.

Add a parameter to a Contact object. It does not copy the contents of the string param.

Note
This function does not duplicate param.
Parameters
homememory home
msip_contact_t object
paramparameter string
Returns
0 when successful, and -1 upon an error.
Deprecated:
Use msg_header_replace_param() directly.

◆ sip_contact_copy()

sip_contact_t * sip_contact_copy ( su_home_t home,
sip_contact_t const *  hdr 
)
inline

Copy a list of Contact header header structures sip_contact_t.

The function sip_contact_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.

Parameters
homememory home used to allocate new structure
hdrpointer to the header structure to be copied

When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.

Example
contact = sip_contact_copy(home, sip->sip_contact);
sip_contact_t * sip_contact_copy(su_home_t *home, sip_contact_t const *hdr))
Copy a list of Contact header header structures sip_contact_t.
Definition sip_protos.h:2896
Returns
A pointer to newly copied header structure, or NULL upon an error.

◆ sip_contact_create()

sip_contact_t * sip_contact_create ( su_home_t home,
url_string_t const *  url,
char const *  p,
  ... 
)

Create a contact header.

Create a Contact header object.

Create a Contact header object with the given URL and list of parameters.

Parameters
homememory home
urlURL (string or pointer to url_t)
p,...NULL-terminated list of Contact parameters
Returns
A pointer to newly created Contact header object when successful or NULL upon an error.

◆ sip_contact_dup()

sip_contact_t * sip_contact_dup ( su_home_t home,
sip_contact_t const *  hdr 
)
inline

Duplicate a list of Contact header header structures sip_contact_t.

Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next) to a list of headers, all the headers in the list are duplicated, too.

Parameters
homememory home used to allocate new structure
hdrheader structure to be duplicated

When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.

Example
contact = sip_contact_dup(home, sip->sip_contact);
sip_contact_t * sip_contact_dup(su_home_t *home, sip_contact_t const *hdr))
Duplicate a list of Contact header header structures sip_contact_t.
Definition sip_protos.h:2853
Returns
A pointer to the newly duplicated sip_contact_t header structure, or NULL upon an error.

◆ sip_contact_format()

sip_contact_t * sip_contact_format ( su_home_t home,
char const *  fmt,
  ... 
)
inline

Make a Contact header from formatting result.

Make a new sip_contact_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_contact_t.

Parameters
homememory home used to allocate new header structure.
fmtstring used as a printf()-style format
...argument list for format
Returns
A pointer to newly makes header structure, or NULL upon an error.

◆ sip_contact_init()

sip_contact_t * sip_contact_init ( sip_contact_t  x[1])
inline

Initialize a structure sip_contact_t.

An sip_contact_t structure for Contact header can be initialized with the sip_contact_init() function/macro. For instance,

sip_contact_t * sip_contact_init(sip_contact_t x[1])
Initialize a structure sip_contact_t.
Definition sip_protos.h:2784

◆ sip_contact_make()

sip_contact_t * sip_contact_make ( su_home_t home,
char const *  s 
)
inline

Make a Contact header structure sip_contact_t.

The function sip_contact_make() makes a new sip_contact_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.

Parameters
homememory home used to allocate new header structure.
sstring to be decoded as value of the new header structure
Returns
A pointer to newly maked sip_contact_t header structure, or NULL upon an error.

◆ sip_is_contact()

int sip_is_contact ( sip_header_t const *  header)
inline

Test if header object is instance of sip_contact_t.

Check if the header class is an instance of Contact header object and return true (nonzero), otherwise return false (zero).

Parameters
headerpointer to the header structure to be tested
Return values
1(true) if the header is an instance of header contact
0(false) otherwise

Variable Documentation

◆ sip_contact_class

msg_hclass_t sip_contact_class[]
extern

Header class for Contact header.

The header class sip_contact_class defines how a SIP Contact header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_contact_t header structure.
